ngtcp2_crypto_verify_regular_token
==================================

Synopsis
--------

*#include <ngtcp2/ngtcp2_crypto.h>*

.. function:: int ngtcp2_crypto_verify_regular_token( const uint8_t *token, size_t tokenlen, const uint8_t *secret, size_t secretlen, const ngtcp2_sockaddr *remote_addr, ngtcp2_socklen remote_addrlen, ngtcp2_duration timeout, ngtcp2_tstamp ts)

    
    `ngtcp2_crypto_verify_regular_token` verifies a regular token
    stored in the buffer pointed by *token* of length *tokenlen*.
    *secret* of length *secretlen* is a keying material to generate
    keys to decrypt the token.  *remote_addr* of length
    *remote_addrlen* is an address of client.  *timeout* is the period
    during which the token is valid.  *ts* is the current timestamp.
    
    This function returns 0 if it succeeds, or -1.
